NEW YORK, ASSIGNOR TO PILSBURY A. WEBSTER, OF SAME PLACE.

FEED-CUTTER.

SPECIFICATION formingpart of Letters Patent No. 412,034, dated October 1, 1889.

Application filed June 7, 1889. Serial No. 313A23. (No model.)

To (@ZZ whom it may concern.-

Beit known that I, JUSTICE W. MARSHALL, of Oazenovia, in the county of Madison, in the State of New York, have invented new and useful Improvements in Feed Cutters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

In said drawings, Figure 1 is a top plan View of my improved feed-cutter. Fig. 2 isa. longitudinal vertical section on line 00 m, Fig. 1; and Fig. 3 is a detached plan view of the feed-roller.

Similar letters of reference indicate corresponding parts.

C represents the usual trough in which to place the feed to be cut. Across the top of the front end of the said trough is secured a stationary knife a, which consists simply of a plain steel bar presenting a square face at its cutting-edge. This knife I preferably arrange adjustable in its position by securing the front portion thereof to the trough by bolts ZZ, passing vertically through the knife and through the side plates of the trough.

The rear portion of the knife is provided with screw threaded openings, in which work set-screws b b, resting with their lower ends on top of the aforesaid side plates. Under the rear edge of the knife to is arranged the feedroller 0, which is extended across the trough O, and has its shaft extending through one of the side plates of said trough, and provided with a crank 12., by which to turn the said feedroller. This feed-roller is provided with win gs c c, which are disposed longitudinally obliquely in relation to the axis of the roller, and said wings are of such widths as to cause them to pass in proximity to the cutting edge of the stationaryknife (1, during the rotation of the feed-roller.

The aforesaid adjustable attachment of the stationary knife a allows the same to be adi justed so as to maintain said knife in proper 45 position to cause the wings of the roller to pass closely to the knife during the operation of the machine.

P represents a plate, which is hinged to suitable supports t, secured to the side plates of the trough and at such a distance from the stationary knife o as to allow the free edge of the plate to lie upon the subjacent feedroller 0. Said plate is made to press on the feed-roller by means of springs i i, secured to the pivotal supports of the plate and bearing on the free end thereof.

During the operation of the machine the feed-roller 0 draws the material to be cut toward the stationary knife a. The plate P, pressing on the material thus carried forward, allows the feed-roller to obtain a firm grip on the material to be cut, and also prevents said material from passing up over the stationary knife (1. By setting the plate P fartherfrom the stationary knife athe feed-roller receives a longer hold on the material to be cut, and thus the cut of the feed is lengthened.

In order to allow the machine to be adjusted for different lengths of cut,l arrange the pivotal supports 13 t of the plate P adjustable toward and from the stationary knife (1-, and in a smaller machine this maybe accomplished by employing screw-eyes for the pivotal supports of the plate and providing the top of the side plates of the trough with a series of holes 0 o, adapted to receive said screw-eyes.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a feed-cutter, the combination, with 8c the t-rough,of a knife extended across the top of said trough and secured thereto, and afeedroller arranged across the trough under the aforesaid knife and provided with wings adapted to pass with their free edges in proximity to the said knife, substantially as described and shown.

2. In a feed-cutter, the combination, with the trough, of the knife a, extended across the top of said trough and secured at its front edge to the same, the set-screws b b, working in screw-threaded openings near the rear edge of the said knife and bearing on top of the trough, and the feed-roller 0, arranged across the trough under the rear edge of the aforesaid knife and provided with wings adapted to pass with their edges in proximity to the knife, substantially as described and shown.

3. In combination with the trough C, the stationary knife a, extended across the top of said trough and secured thereto, the feed-roller 0, arranged across the trough under the rear edge of the aforesaid knife and provided with wings c c, disposed longitudinally obliquely in relation to the axis of the roller and adapted 'bl y toward and from the aforesaid knife, the

plate P, pivoted to the aforesaid supports and resting with its front end upon the feed-roller, 15

and springs 2' 2", pressing the said plate toward the feed-roller, substantially as described and shown.

In testimony whereof I have hereunto signed my name this 29th day of May, 1889.
